Switch and providers?

Question

Computer networks

Hello.
If we imagine that there are a certain number of providers (2-10) and one good switch.
What will happen if all providers are put into this switch?
Is it possible to increase network bandwidth?
Does this make sense, or are there other methods that implement this?
With respect to you, beloved Toasters!)

Answer 1

If you do not set it up correctly, they will call and ask you to remove the excess from the power-on port, or simply nothing will happen.
A good switch can only help if you have your own AS, a block of addresses, and you will accept / give away BGP routing.
In all other cases, you need a router, moreover, with support for Wan Load Balancing via NAT, but you can only increase the total bandwidth of several connections (it will most likely work on torrents, but not on a single-threaded file download, run into the limitation of one of providers).

Answer 2

The switch, in principle, is not for this, the end equipment will work with only one, or statically prescribed settings, or with the DHCP provider that will respond first. So the question is not correct. And about link aggregation, you can read about LACP or EtherChannel.

What will happen if all providers are put into this switch?

The switcher can't handle it. Well, except that all providers will issue VLANs. You need a router with two or more WAN ports. Needless to say, such specialized solutions are fabulously expensive. Therefore, take a more powerful router and flash it in OpenWRT + MultiWAN .
You can also take any Mikrotik, but it will only chew 250 Mbps PPPoE or 400-600 Mbps without VPN (FastTrack).
On OpenWRT, the speeds are also not terrible, since he has not yet learned how to support Hardware NAT.
Yes.

I had a boss...
He had two providers at his head office...
There were white addresses on workstations and servers...
From both providers....
He didn't know what wealan, stp, routing, spanning three are ...
By nationality, he was a Moldovan ...
So what am I ... will not .... even if the switchboard is very good.
